Jun-ichiro “itojun” Hagino who as a core developer of the KAME project which enables IPv6 on BSDs, died Oct. 29th 2007. He was 37 and was living in Tokyo, Japan.

He was a hacker. A distinguished hacker. He served as a member of Internet Architecture Board which makes decisions on Internet specifications (RFCs).

Itojun was one of the only few Japanese developers well-known all over the world. He used his network to introduce Japanese developers to world wide developers.

His passion was not limited in programming. He had a good appetite for Asian foods. He was a founding member of ESD, Japan’s first restaurants review site, too.

Itojun was a symbolic person of Japanese early Internet users. We loved you and will miss you, itojun.

Mochio Umeda lives in the Bay Area but he is very influential in Japan. His best selling book, ‘Web Shinkaron’, was excitedly accepted by business people.

His word is straight-forward and impassioned. He describes what is Google, what is the Web 2.0, what is open source. Those things were not well understood by the Japanese older business populations.

Joi Ito is the best known Japanese visionary and blogger in the world but Umeda is a much more well-known visionary inside Japan.

Umeda is doing some consulting and also runs a VC firm. Umeda is a board member of the Japanese web startup ‘Hatena’.

Kakaku.com started from a website which lists the retail prices of Akihabara, the Japanese electric market. It quickly became a famous site which shows the best deals of electrical products.

Their revenue sources are through affiliate and advertisement. Now Kakaku.com is not specialized in electric products. Their business was expanded into travel, insuarance, and foreign currency trade.

A founder of Kakaku.com is not a famous person. Mitsuaki Makino created Kakaku.com in 1997 and made the site profitable, then quietly retired from CEO in 2002. Yoshiteru Akita took the position of CEO and successfully grew Kakaku.com into a public company.

In 2005, Kakaku.com was cracked and customers’ email addresses were leaked. The site was closed for ten days. The company’s awful explanation upset their customers.

Here is the English version of the financial statement. It’s worth a look.
